21. CONNECTING A RAIN SENSOR
Most “normally closed” rain or soil moisture sensors can be connected to the
710A controller. The function of the sensor is to prevent automatic watering by the
set program due to excessive rainfall or when the soil is too moist.
To connect the sensor to the controller, please follow these steps:
1. Cut the yellow wire loop that exits the controller in the middle of the loop.
2. Strip approximately 1/2″ of insulation from the end of each wire.
3. Splice one yellow wire to each of the wires coming from the sensor.
Use waterproof wire connectors to secure the connections.
4. Follow the sensor manufacturer’s instructions for calibrating the sensor.
5. When the sensor is active and preventing automatic operation, a icon will
appear on the display.
The icon will only appear when the sensor is active.
Recommended rain sensors are the Rain Bird RSD and Hunter Mini-Clik
Recommended soil moisture sensor is the Irrometer WEM-B
